PDFPrint

public PDFPrint(String fileName,
        IPassword password)
         throws PDFException

Loads a PDF document from a file.

Parameters:

fileName - Name of the PDF file.

password - An object that provides passwords to open the document, leave null if not needed. When working with documents that have no passwords, the host application should pass null for the value of this parameter. When documents are known to have passwords, the host application should pass an instance of the PDFPassword class that can hold a single password or a list of passwords.

Throws:

PDFException

Parameters:

inStream - InputStream to read the PDF document.

password - An object that provides passwords to open the document, leave null if not needed. When working with documents that have no passwords, the host application should pass null for the value of this parameter. When documents are known to have passwords, the host application should pass an instance of the PDFPassword class that can hold a single password or a list of passwords.

Throws:

Method Detail

print

public static void print(String fileName,
         PrintSettings printSettings,
         IPassword password)
                  throws PrinterException,
                         PDFException

Convenience method to print a PDF document from a file. This method will prompt the user with the printer dialog and then print the document. This method is equivalent to:

PDFPrint pdfPrint = new PDFPrint (fileName, pwdHandler);
pdfPrint.print (printSettings);

printSettings - Print job settings. Use this object to tell the library how to print the document. The library uses default settings when null is used.

password - An object that provides passwords to open the document, leave null if not needed. When working with documents that have no passwords, the host application should pass null for the value of this parameter. When documents are known to have passwords, the host application should pass an instance of the PDFPassword class that can hold a single password or a list of passwords.

Throws:

PrinterException

         PrintSettings printSettings,
         IPassword password)
                  throws PrinterException,
                         PDFException

Convenience method to print a PDF document from a file to a named printer. This method is equivalent to:

PDFPrint pdfPrint = new PDFPrint (fileName, pwdHandler);
pdfPrint.print (printerName, printSettings);

Parameters:

fileName - Name of the PDF file.

printerName - Name of the printer to print to. If null, prints to the default printer.

printSettings - Print job settings. Use this object to tell the library how to print the document. The library uses default settings when null is used.

Throws:

PrinterException

PDFException

print

public void print(PrintSettings printSettings)
           throws PDFPermissionException,
                  PrinterException

Prints this PDF document. This method will prompt the user with the printer dialog and then print the document.

If finer control of printing is necessary, the PDFPrint object implements both Printable and Pageable (through the getPageable method). The host application can then create its own PrinterJob and set any settings necessary, then call either setPageable or setPrintable and then start the print job.

Parameters:

printSettings - Print job settings. Use this object to tell the library how to print the document. If null, the library will print using default settings.

Throws:

PDFPermissionException

PrinterException

print

public void print(String printerName,
         PrintSettings printSettings)
           throws PDFPermissionException,
                  PrinterException

Prints this PDF document to the specified printer, by name. This method will print the PDF document silently (without showing the printer dialog) to the named printer. If the printerName parameter is null, this method will print to the default printer.

This method can only be called if using Java 1.4.2 or higher as it needs PrintServices, which were only implemented starting on 1.4.

If finer control of printing is necessary, the PDFPrint object implements both Printable and Pageable (through its getPageable method). The host application can then create its own PrinterJob and set any settings necessary, then call either setPageable or setPrintable and then start the print job.

Parameters:

printSettings - Print job settings. Use this object to tell the library how to print the document. If null, the library will print using default settings.

printerName - The name of the printer to print to. If this parameter is set to null, the method will print to the default printer.

Throws:

PrinterException - This exception is thrown if the printer is not found or if there is an error while printing.

PDFPermissionException

print

public void print(String printerName,
         PrintSettings printSettings,
         PrintRequestAttributeSet printAttrSet)
           throws PDFPermissionException,
                  PrinterException

Prints this PDF document to the specified printer, by name and passes the attribute set to the printer job. This method will print the PDF document silently (without showing the printer dialog) to the named printer. If the printerName parameter is null, this method will print to the default printer. If the printAttrSet parameter is null, the printer job will use its default settings.

This method can only be called if using Java 1.4.2 or higher as it needs PrintServices, which were only implemented starting on 1.4.

If finer control of printing is necessary, the PDFPrint object implements both Printable and Pageable (through its getPageable method). The host application can then create its own PrinterJob and set any settings necessary, then call either setPageable or setPrintable and then start the print job.

Parameters:

printSettings - Print job settings. Use this object to tell the library how to print the document. If null, the library will print using default settings.

printerName - The name of the printer to print to. If this parameter is set to null, the method will print to the default printer.

printAttrSet - The attribute set to pass to the printer. This parameter simply gets passed through to the printer job to set options such as the media tray, chromaticity and others. If null is passed, the print job will use default attributes.

Throws:

PrinterException - This exception is thrown if the printer is not found or if there is an error while printing.

PDFPermissionException

printToDefaultPrinter

public void printToDefaultPrinter(PrintSettings printSettings)
                           throws PDFPermissionException,
